ADS-B Out, are you prepared for the change?

ADS-B OUT (Automatic Dependant Surveillance – Broadcast) requires that the aircraft transmits its own GPS position via the Mode S transponder, regardless of whether the aircraft is being interrogated by a ground radar or by other aircraft’s TCAS. The GPS source must meet high accuracy and integrity requirements only available from a qualified WAAS GPS.

The European airspace mandate for ADS-B Out is effective from June 2020, and from January 2020 for US operations.
